Final answer:
Underdosing refers to taking less than the prescribed dose of a medication or drug, deliberately or by mistake.
Step-by-step explanation:
Underdosing refers to taking less than the prescribed dose of a medication or drug, either deliberately or by mistake.
If someone intentionally takes less than the prescribed dose, this can be considered underdosing.
However, underdosing can also occur if someone accidentally takes less than the prescribed dose due to a mistake or misunderstanding.
Underdosing can have consequences such as reduced effectiveness of the medication or inadequate treatment of the condition for which it was prescribed.
